It works, I have verified it many times, because many times I have the same recording on different media. Days ago I checked again with the CD and vinyl:
Jan Garbarek & The Hilliard Ensemble - Officium (1993)
The DR values matched exactly for each track. By the way, the sound of the CD is better than vinyl 2014 pressing.
